14.1 Measurement Types
Each of the UltraTEV Monitor ™ channels collects a variety of different measurements and these are
recorded in the summary table. The following table explains what each of these different
measurement types is.
Maximum
Level This is the maximum of the Maximum Amplitude (dB for TEV, pC for Cable
PD) of samples.
Average Level This is the average of the Mean Amplitude (dB for TEV, pC for Cable PD) of
samples.
Maximum PPC This is the maximum of the Maximum Pulses Per Cycle of samples.
Average PPC This is the average of the Mean Pulses Per Cycle of samples.
Total 1
st
Count This is the total of the First Counts of the samples.
% Total Events This is the Total First Count for the channel divided by the Total number of
pulses detected by the system. Note that the total number of pulses detected
by the system is the sum of TEV or Cable PD event count of the samples.
% 1
st
Count This is the percentage of the total number of pulses that this channel
detected first.
Maximum STS This is the maximum of the Maximum Short Term Severity of samples.
Average
Overall
Severity This is the average of the Overall Severity of the samples.
